What does the 'Group by' feature do within report filters?

The 'Group by' feature within report filters is designed to summarize data based on specified fields. When utilized, this feature enables users to aggregate data into categories, allowing for a clearer understanding of trends and patterns within the dataset. For example, if a report includes sales data, using the 'Group by' feature to organize the data by region or product category will provide a condensed view that highlights total sales figures per group. This summarization facilitates easier analysis and more informed decision-making, as it reveals insights that might otherwise be obscured in raw data.

Other features mentioned, such as deleting duplicates, segregating into different reports, or sorting alphabetically, serve different purposes and do not focus on summarization. Deleting duplicates removes redundant entries, while segregating data would imply a division into separate datasets, and sorting data addresses the order rather than the aggregation of information. Thus, the primary function of the 'Group by' feature is to categorize and summarize data effectively.
